To all whom it may concern:

Be it known that I, WILLIAM G. K'oon, a

citizen of the United States, residing at Milwauke'e, in the county of Milwaukee and 5 State of Wisconsin,have invented new and useful Improvements inMetal-Coated- Sheets, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a pint ofthis specification.

y invention relates to metal coated sheets and more specifically to bronzed paper.

One of the obj ts of m invention is to make such a sheet in which the metal coating will h veabrilliant and glossy-appear- Further-objects will appear from the de- 7 description to follow taken in connection with the appended claims.

'In the drawings in which one embodiment of my invention is shown; 1 is a side elevation showing diagrammatically. an app bronzed paper embodyin my invention; 1 Fig. 2 1s a plan view o a composite sheet, different layersbeing partly removed'to show the construction; and

Fig. 3 is a cross section of a composite sheet embodying my invention showing the different layers.

The fim's ed sheet. comprises a of layers 1 11, 12 and 13, the yer 10 forming the base of any suitable material such as .paper, the layer 11 being a coating of any. suitable adhesive such as varnish, the layer 12 being. a coating of pulverized metal such asbnonze, and the'layer 13 being a coating of p v or any other suitable material'impervlous to the adhesive layer 11 lying between the, adhesive layer' and the layer 10 to preven the varnish from soak- -i'ng' in the pores of the paper.

If the varnish were applied next to the pores of the rough, and a coating of metal such a ro brilliant gomy ap arance which it has when the coating o egum or other impervih to the paper between the adhesive coating and the paper. The apparatus shown in Flg. I for making the composite metal coated sheet comnshmglmachiilile, r pp ymg nished sheet.

22 which dust of the surplus meta aratus for. making,

'I cl plurality the varnish applied to surface would not have the" on sai first coating, verized metal superposed on said. adhesive prises a machine 14 for applying the varnish to the gummed paper, aiplurality of drying rollers 15 over which the varmshed paper passes after'it has passed through the var- The varnishing machine 14 comprises a roller 17 which revolves in a bath of varnish 18, and a pressure roller 19 which holds the gummed sheet against the Tvarnishing roller.

The bronzing machine comprises .a compartment or hopper 20 containing a sup ly of powdered metal, a revolving brush 21 ibr sweeping spreading it on the sticky varnished paper, and a plurality of revolving finishin rollers and at thesame time give the surface a sli ht burnishing. The'sheet may be unwoun from a roll 23 and wound up on a roll 24. The urpose of the rollers 15 isto 've' the varnish a chance to set somewhat be ore the powdered metal is applied.

Having thus described my invention what aim as newand desireto secure by LettersPatent is;- H Y 1.
